Thousands of people drove, boarded packed trains, walked and biked to San Francisco’s Chase Center on Friday evening for a much-anticipated Metallica concert — the first major event at the new Golden State Warriors arena, and the first test for whether the Bay Area’s mass transit systems could transport an influx of passengers to the event on time and without incident.

Many arrived early and in good spirits, and reported relatively smooth rides getting to the arena.

“It’s amazing,” said Ricardo Adolfs as he stood in the front courtyard of Chase Center. “It’s f— amazing.”

Adolfs, 38, flew from Brazil to Los Angeles earlier this week with his family. They drove up to San Francisco to stay with his friend, who dropped him off about a kilometer away from Chase Center. He walked the rest of the way, stopping to take selfies in his Metallica tank top. He planned to call for an Uber after the show ends.

“Do you know where I can get a beer?” he asked a reporter.

Adolfs was one of about 16,000 people inside the arena, which seats 18,000 for games.

Traffic getting there was manageable — one couple jumped out of a Lyft along Terry A. Francois Boulevard just after 8 p.m. and said it took them about 15 minutes to go from Union Square to Chase Center.

“Not bad at all,” the husband said.

Yamil Tejeda flew from the Dominican Republic to San Francisco on Thursday to attend his first Metallica concert. Wearing a black Metallica T-shirt and backward red baseball cap, he said his all-time favorite Metallica concert was the first combined effort with the San Francisco Symphony in 1999, so he decided he had to attend this one.

Tejeda, along with two-thirds of the T-line, got off at the Chase Center stop as police officers stood on the platform with a police dog. After entering the courtyard, he walked up some amphitheater steps and snapped photos of the giant video screen on the front of the arena. He planned to take the Muni train back after the show ended.

San Francisco police Assistant Chief Mike Redmond stood in the front courtyard and watched the few stragglers wandering through a couple of dozen security gates at the front entrance.

“There’ve been no issues with security or traffic as far as the beginning of the event,” he said. “A lot of people showed up early just to see the new arena.”

Muni has plans for express buses to quickly take attendees to BART stations, similar to the old days at Candlestick Park, he said.

“It’s the first day and we’re taking a look at it as well,” he said. “We’re hoping for a safe event.”

Nick Richardson, 49, stood along the main entrance path with his bike, trying to score an extra ticket from the steady flow of people.

“I’m a show fan,” said Richardson, who lives in San Francisco. “It looks really cool. A great first impression.”

It took him about 15 minutes to pedal his Trek hybrid from his Mission District house to the arena. He said the trip was obstacle free and typical of a Friday.

“I own a car, too, but I prefer to bike,” Richardson said. “It’s the city we live in.”

As throngs of people streamed into the courtyard — which also had a Guitar Hero station, a merchandise stand and countless selfie-taking fans — yellow-vested traffic control officers helped move cars through the roads and guide pedestrians.

Nick Thompson, 36, was fixing his pedi-cab pedal outside Chase, after dropping off a couple. He said he’d picked up a few fares to the concert, mostly from the Ferry Building.

“It’s pretty similar to a Giants game,” he said.

The ride was smooth with a designated bike lane the whole way, he said. What wasn’t clear yet was where exactly he should pick up and drop off fares. He planned to pick up more customers when the concert let out.
